Curated OER
Chemistry: Metals and Non-Metals
Students conduct an experiment to test the reactivity of metals and non-metals. In this chemistry activity students test metals with different chemicals to observe the reaction. The results are used to categorize the metals.

Solubility and Chemical Changes in Groundwater
Middle schoolers test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH...

A Solution for Moles
Students calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.
Curated OER
pH Potential
Students experiment to determine the positive and negative impacts of human activities on environmental change. They examine how physical and biological processes such as decomposition affect soil characteristics while looking at the pH...
Curated OER
Water Quality Monitoring
Young scholars study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.
Curated OER
Is There Really Life on Mars?
Students examine the work of scientists and determine how they test their theories.
